Sessions at the General Assembly Related to Recent Natural Hazard Events

There are two additional Union Symposia (US) that have been added to the EGU General Assembly 2011 Programme.

Union Symposia 4 (US4) The 22 February 2011 Christchurch Earthquake will be in Room D, on Thursday 7 April from 08:30–10:15.

Union Symposia (US5) The 11 March 2011 Tohoku (Sendai) Earthquake and Tsunami will be in Room D, on Friday 8 April from 08:30–10:00.

For both sessions further details will be available soon.

Experiences of the EGU General Assembly

For those of you who maybe attending the General Assembly for the first time, you may be wondering what it’s like from a participant’s point of view. The short piece below gives one person’s views of attending the General Assembly in 2010.

I attended EGU last year for the first time. When I arrived there the feeling was just ”WOW!”. EGU General Assembly is such a huge conference!

The first day I had to adjust to the mass of lectures and posters, to select which session to attend. But after that it was just so interesting! So many different topics, so many scientists from all over the world!

I took the opportunity to listen to lectures given on volcanoes, freak waves and on contamination of the atmosphere (just a few examples). I really liked the poster sessions. Hundreds of different research projects displayed together. There was the chance to talk to the scientists and to get information on how they did their research.

I had a poster of my own to present. At the beginning of the session I was a little nervous: would people be interested in what I did? Would they think that my work was good? Or would they just walk by and ignore me?

But when the first person stopped and started to ask me about my project, such an interesting discussion came up and it is fascinating how an outsider sees things one does not see himself/herself. I was asked many questions and I stopped feeling self-conscious. That was a great help to me. And I have to admit that I was a little bit proud to present my research in such an environment, such a big conference! This was definitely a great experience to me.

Weblinks relevant to the Sendai Earthquake and Tsunami [Updated 31 March]

This blogpost is a round-up of potentially useful weblinks to information about the Sendai, Japan earthquake of 11 March 2011. This post is a summary of what is out there as a resource, not European Geosciences Union endorsed links.

There is a Supersite for the Sendai Earthquake which is a collection of preliminary data and research. This has a lot of information contained within the page and links to other pages.

This includes the USGS event homepage, which has maps of seismic activity and a summary of the event. The USGS also has a map and list of Earthquakes in the Asia region which shows aftershocks.The Japanese Meterology Institute’s page on the Earthquake now has more information. A preliminary model of the faults that were involved in the earthquake can be found at the USGS site .

Concerning the tsunami, the Pacific Tsunami Warning Center, from NOAA has its own pages. Tides for various US states and dependencies can be found online.

The Global Disaster Alert and Coordination System has various models related to the earthquake and tsunami.

Various sites have satellite imagery to show the impacts of the Geohazards. NASA’s Earth Observatory has collected it’s images together.

IRIS has lots of resources designed for teaching, including a powerpoint presentation and animations. The Harvard Seismology Site also contains research and animations.

A good summary of the situation at the nuclear power plants can be found at the New York Times webpage.

The Geoblogosphere has covered the events in detail. The AGU blogs cover different aspects of the event: Dave Petley’s Landslide Blog, Callan Bentley’s Mountain Beltway Blog, and Dan Satterfield’s Wild, Wild Science. The Geographile Blog has a video of liquefaction. Interesting information is also to be found on the Berkeley Seismoblog.

[16th March updates]

The History of Geology blog has a post on the history of earthquakes in Japan. Clear diagrams and maps are available on the New York Times webpages.

The International Atomic Energy Agency (IAEA) has updates on the situation at the Nuclear Power Plants. There are live news updates available from many sources including the BBC, the Japan Broadcasting Corporation’s English Pages have several news stories and videos.

Concerning the Tsunami, the Japanese Meterology Institute issued a major Tsunami warning (with evacuation) only 3 minutes after the earthquake, and provided the estimated time of arrival of the Tsunami at the coast, and its expected height (4 m) after the earthquake. The JMA’s Tsunami forecasting is based on observational network and on efficient models.

At the Sendai Supersite, there are earth observation maps, including several maps of GPS data showing seismic shifting, one map was constructed using 20Hz GPS data of a DLR station (German space agency). Other images that show the impact of earthquake and tsunami include: Flooding along the Kitakami River, Japan, Tsunami Damage near Ishinomaki, Japan, Flooding from Tsunami near Sendai, Japan and Earthquake and Tsunami near Sendai, Japan.

[31 March Update]
Earthquake Reports covers the socio-economic losses, human impacts and general news and analysis of the quake in a series of reports.
